I agree with Stoneke, the Hawken is much harder to build correctly than it looks. To me, all the hard work is in the tang, breech, lock, and mortis areas. The tang, breech, and lock combination are hard to inlet and get the right relationships with no gaps. Then you have to be able to remove the barrel without the tang moving slightly forward during the process resulting in gaps. Tight inleting is a must as well as the tang / hooked breech fit. Also, getting the correct width of the front mortis cross section verses the back mortis cross section is a bit tedious. However, a well built Hawken is an accurate neat rifle well worth the effort. I continually switch back and forth between Hawken, Southern Mountain rifles, and Virginia rifles. I am hooked on all three, must be that I like Iron Mounted Rifles!!! The drawing of the S. Hawken rifle available from "The Hawken Shop" is a good reference to use when building a Hawken.
